An Angel and a demon. The two couldn't be more opposites. Yet, they seem drawn to one another, unable to stay away. When the angel Gajeel and the demon Levy meet, they are determined to stay enemies. As is the nature of demons and angels. But, something keeps luring them back to each other, and neither one is able to stop it. Eventually, the two break the ultimate rule of both of their worlds: do not fall in love. Unable to stay away from each other, the two fall into a doomed romance. One which is more passionate than either of them ever intended--or that they care to control. When their secret gets out, along with an ancient evil that they can't face alone, will the two be able to stay together? Or will fate tear them apart?
